During the manufacturing of large structures such as launch vehicles, spacecraft, and propellant storage systems, it is often necessary to add external features such as brackets during the manufacturing process. Depending on the material used for the structure, features such as brackets can be attached using traditional techniques such as TIG welding. However during conventional fusion welding, there is always a danger that distortion can occur, or that the poor weldability of the material can result in a significant loss in mechanical performance or weld integrity.

• • HiPeR  AdPack Strap to be applied as thermal interface between component and structure

The aim of the activity, developed by Omnidea-RTG in conjunction with ESA, Pleione SA and Fraunhofer IVV, was to produce a thin film polymer-based product enhanced with Graphene nanoparticles to decrease He gas permeability while maintaining thermal bonding properties and without major penalties in UV resistance, for use in high-altitude inflatable structures. The proposed technological application is the usage of this thin film as envelope inner layer for high altitude airborne platforms which, from a lower altitude (vs.

Electrical contact materials used today for sliding electrical transfer applications have been developed in the 60/70th and are procuredfrom USA.It is believed that the latest manufacturing capabilities available in Europe are able to manufacture some new class of sliding contact material alloys. This activity propose to test the most promising European materials developed for sliding electrical contact applications.

The spatial distribution and quantity of in-situ lunar resources, such as water, ice and ilmenite, is currently highly uncertain. The VMMO (Volatile and Mineralogy Mapping Orbiter) is a low-cost 12U Cubesat that includes both the Lunar Volatile and Mineralogy Mapper (LVMM) science payload, a GNSS technology demonstrator, and the supporting 12U Cubesat platform. This GSTP activity addresses the need for mapping these lunar volatiles at relatively high spatial resolution in permanently-shadowed regions by using active single-mode fiber-lasers.

Due to an increasing power and complexity, electrical harnesses in aerospace systems require mass and volume optimization. The harness mass performance is driven by the ampacity (or current rating), that is the maximum current a wire or cable is able to carry without exceeding its maximum operating temperature. This current depends on the environment (pressure, temperature…), the wire’s physical characteristics (gauge, dielectric, overall diameter…) but also on the number of wires routing in the same bundle.
